Splints that are too tight or too loose

If a splint cannot be made to fit by adjusting the angle of the rings (see Adjustment Flyer), the overall splint size should be increased or decreased by at least a whole size. Use the return instructions on the back of the packing slip or invoice to exchange the splint.

How tight should splints be? DIP splints should be very snug since they can slide off during functional activities. PIP and thumb IP splints should be comfortably snug. These are general guidelines; there are always exceptions.
